Danni records the number of bedrooms and the number of televisions in 11 houses. She has these data that she needs to show as a graph or chart.

Danni has collected paired numerical data: for each house, she has a value for the number of bedrooms and a value for the number of televisions. The purpose of plotting this data would be to see if there is a relationship (correlation) between the two variables (e.g., do houses with more bedrooms tend to have more televisions?). A scatter diagram is the standard statistical tool for visualising the relationship between two quantitative variables. Each pair of values is plotted as a single point on the graph.
